Good evening everyone and welcome back to TFB’s Silencer Saturday brought to you by Yankee Hill Machine, manufacturers of the YHM Turbo K 5.56 rifle suppressor. Last week we got a look at the updated SilencerCo Osprey 2.0 with the push button indexing system. This week we are getting ready for fall with the SilencerCo Harvester EVO. While we aren’t actually hunting today, we are being very quiet. Let’s see if the EVO is right for you.

SILENCER SATURDAY #241: Be Very Quiet, We’re Hunting With the SilencerCo Harvester EVO

Even though I buy my license, tags, and stamps every year, It has been way too long since I have actually gone hunting. As you get older, the work days are long and time with friends and family is short. But every summer I have the urge to scout for deer in preparation for a fall harvest. And while many parts of the Northeast are so heavily populated that hunting is relegated to shotgun and archery seasons, if you go far enough north, rifles – and suppressors – are allowed by regulation.
We could run a whole series on rifle hunting with suppressors, probably hosted by Adam and/or Rusty from TFB and our sister sites AllOutdoor and OutdoorHub respectively. But while we have the Harvester EVO in house for a pre-hunting season review, let’s take a look at some important requirements for a dedicated hunting suppressor. First, a look at the numbers.

1. A good hunting suppressor should be light.
The SilencerCo Harvester EVO weighs in at slightly more than 11 ounces, a beautiful weight for a hunting rifle, especially if you are using long barrels of 20 inches or more. Even if your hike to the stand or blind is measured in yards and not miles, a light suppressor at the end of your barrel will help with balance and keeping a steady sight picture. In addition, a lighter silencer will mean less point of impact shift if you zero your rifle suppressed. A tubeless design similar to the Omega 9K definitely helps to save on weight.

2. A good hunting suppressor must be strong.
Manufacturing a dedicated hunting rifle suppressor means planning for large calibers and magnum cartridges. The SilencerCo Harvester EVO is built with Cobalt 6, Inconel, and stainless steel to handle anything from 5.56×45 to .300 Winchester Magnum. Two direct thread adapters are included for a variety of hosts and the ability to use the Bravo and ASR mounts also open up some quick disconnect options as well.
3. A good hunting suppressor has to be accurate.
Missing a shot when you are shooting at paper targets could result in a bad score. Missing a shot while you are hunting could mean losing your one chance at a big buck, or worse, wounding an animal that gets away. In a perfect world, adding a suppressor to your action, chassis, ammo, and optic system should result in no changes in accuracy. Heavier suppressors can pull on the end of the barrel, shifting the POI. Some baffle designs can also slightly alter bullet trajectory.
After zeroing my 300BLK Remington Model 7, my first stop was to gauge POI shift. Here’s three shots without the EVO. All of today’s shots were taken from 80 yards, standing, using a small tree as a support to simulate a stalking/field situation.
And three shots with the EVO. Five shot groups would be a better measurement, but I’ll take this result as basically no shift between unsuppressed and suppressed setups.
Hunting ammo is expensive, so it’s nice to be able to practice with training rounds before the season begins. I wanted to see if there was any POI shift between bullet weights and designs. While not necessarily a suppressor issue, it’s a way to judge the size of an impact shift when one variable in your system changes.
Again, no POI shift was detected.
Hunting with subsonic ammunition is tough and should be left to experienced hunters at limited ranges and on appropriately sized game. If you decide to hunt as quietly as possible, my recommendation is to use the Discreet Ballistics 188gr Selous All Copper round.
Again, no noticeable POI shift.
A better choice for most hunters is a fast moving round with proven expansion. For 300BLK, the Barnes 110gr TAC-TX round is recognized as a solid ethical hunting round.
Look at that little snapper.
Traveling at least 1,000 fps faster than the subsonic rounds, the Barnes TAC-TX impacted about six inches above the other tested rounds. They also seemed to shift about an inch to the left.
4. A good hunting suppressor has to be quiet.
Last but not least, the SilencerCo Harvester EVO is quiet. In fact, with subsonic ammunition the EVO is silly quiet. Using paper targets backed by rubber blocks, the impact of the bullet was much louder than the report itself. The Barnes TAC-TX, traveling at around 2,200 fps, was still fairly quiet. I am an advocate of using hearing protection with all supersonic rifle rounds, but if you have to take a shot in the field with the Harvester EVO, your ears won’t ring and you won’t anger the duck hunters by the pond. It’s a great sounding can.
The SilencerCo Harvester EVO is light, well built, displays very little POI shift with 300BLK ammo on this bolt action host, and is very quiet. With a street price sitting at under $600, I have no problem recommending the EVO to any rifle hunter shooting .30 caliber or smaller rounds. Buy with confidence.
Thanks for reading. Be safe, have fun, and we’ll see you back here next weekend for another Silencer Saturday.
